Helpful Positive Review Nice for the money by Gary K, November 23, 2022
Looking for a great price on a decent optic of this type you cant beat this one. prism sights are often way too expensive for good quality. this one is worth it. I wish it had lens covers and was a little higher mount.

Helpful Positive Review excellent red dot! by Richard G, Verified Owner, November 24, 2022
I needed a 100 yard optic for a 10/22. I’m holding a 3” group now with the 3x 1moa ret. Very clear glass. Use it on lowest power green or red. Very tactile windage and elevation adjustments. Will purchase again for another CQB platform.

Helpful Positive Review 2nd as good as the first by Chad, Verified Owner, January 20, 2024
This is my second Monstrum optic and I'm happy to say that I am as or maybe even more impressed with this one than my first. Very nice matte finish, all metal construction, quality glass, and the overall size is perfect on my Aero 16" upper.

Helpful Positive Review Review of wrong reticle by Angler, Verified Owner, August 1, 2020

Helpful Positive Review Monstrum S330P by T J, April 3, 2023
This is the second one that I have purchased in a month. This by far the best red dot on the market. Wish I had known about this red dot. Wish I had known years ago about this before I bought my expansive scopes. Clear vision and no problems with eit...

Product Info for Monstrum S330P 3X Prism Scope

The Monstrum Tactical S330P is a compact, yet heavy duty prism scope with a fixed 3x magnification and a 30mm objective lens, ideal for rapid mid range target acquisition out to 500 yards. These Monstrum Prismatic Red Dot Sights use a glass prism optical system rather than a refracting lens system like traditional scopes, allowing for better optical quality in a much smaller package. With crystal clear optics, an adjustable focus lens, and a comfortable eye relief of 3+ inches, it is comparable to sights several times the price.image
